I have a problem with the RADEditor.
We are using version 2012.607.35 of the Telerik.Web.UI and its seems that the RADSlider in Image Manager is not picking up the strings from RadEditor.Dialogs.resx and the localized counterparts for example RadEditor.Dialogs.de.resx.
This problems seems to be on your localized demo as well(see screenshot from http://demos.telerik.com/aspnet-ajax/editor/examples/localization/defaultcs.aspx
No matter what I do the text does not change.
Do you know of a workaround I could use to fix this and get localizes strings for the slider in Image Manager?
